What factors affect the life of centrifugal fans?
Jun 21, 2025
The service life of centrifugal fans directly affects the operating efficiency and cost of enterprise equipment. Its life is affected by multiple factors. The following summarizes the key factors based on the technical experience of Wuxi JN Fan Factory:
1. Design and manufacturing quality
Material selection: Wuxi JN Fan Factory uses corrosion-resistant and wear-resistant materials such as stainless steel and high-strength alloys to reduce losses in long-term operation. Inferior materials are prone to deformation or cracking of components due to high temperature and corrosion.
Structural design: The dynamic balance accuracy of the impeller, the sealing of the bearing system and the heat dissipation design directly affect stability. JN Fan optimizes the flow channel through CFD fluid simulation, reduces vibration and friction, and extends the life of core components.
2. Use environment and working conditions
Medium characteristics: When the conveying gas contains dust and corrosive components, it will accelerate the wear of the impeller and the casing. JN provides customized solutions for anti-corrosion coatings or special materials to adapt to complex working conditions.
Temperature and pressure: Overload operation (such as long-term higher than rated pressure) will cause motor overheating and bearing failure, and the fan selection must be strictly matched with actual needs.
3. Installation and maintenance level
Installation accuracy: Uneven foundation and excessive pipeline stress can easily cause vibration. Jieen recommends that a professional team install it and use a shock-absorbing base and flexible joints.
Maintenance frequency: Regularly cleaning the impeller dust, replacing lubricating grease, and checking the bearing status are the keys to extending life. Jieen provides an intelligent monitoring system to warn of abnormal vibration or temperature rise in real time.
4. Operational norms
Improper operations such as frequent start-stop and instantaneous overload will greatly shorten the life. It is recommended to configure a frequency converter to achieve soft start and train operators to use it according to regulations.
Wuxi JN Fan Factory's Optimization Solution
- As a professional manufacturer, JN improves the life of fans through the following measures:
- Strictly control the manufacturing process: quality inspection of the entire process, 100% dynamic balance test of the impeller;
- Customized service: recommending the appropriate model and protection plan according to the user's working conditions;
- Lifelong technical support: providing maintenance guides and remote fault diagnosis.
The life of centrifugal fans depends on the full chain management of "design-selection-use-maintenance". Choosing reliable brands (such as Wuxi JN Fan) and standardizing operations can significantly reduce the failure rate and the life can reach more than 10 years.
